Question

Which one of the following is manufactured by the electrolysis of fused sodium chloride [CPMT 1979, 83, 91]
A) NaOH B) NaClO C) Na D) NaCl{{O}_{3}}

Answer 1

Hello Dear.

Here is the answer---

••••••••••••••••••••••••

》Answer --- Option C. Na (Sodium)

》Explanation- During the electrolysis of the fused sodium chloride, sodium which forms an Cation is deposited in the Cathode and chlorine which forms an anion deposited at an anode.

Electrolytic Dissociation 》》》

NaCl •••••》 Na+ + Cl-

☆ Reaction at cathode》

○○○ Na+ + e- ••••••》Na

☆ Reaction at anode 》

○○○ 2Cl- - 2e- •••••••》Cl2

Thus, from these reaction, we can say that Na is evolved at Cathode.

Thus, Option C. is correct.
